Phosphorus (P) is present in different chemical compounds in animal feeds, and the solubility and digestibility of these different compounds are known to differ significantly. Animal protein ingredients generally have a high P content and are major contributors to total P of feeds for fish and other domestic animals. Estimation of different P compounds in these ingredients could help to improve...

Enteral nutrition support is a critical component of modern burn care for severely burned patients. However, tube feeds are frequently withheld during the perioperative period because of aspiration concerns. As a result, patients requiring multiple operative procedures risk accumulating significant protein-calorie deficits. The objective of this study was to describe our American Burn Associati...

Lactating dairy cow diets with more than 24% starch (DM basis) are common, but recent high corn prices have fueled a desire to feed lower-starch diets. The potential for using digestible neutral detergent fiber or pectin from byproduct feeds or sugars to partially replace starch from corn grain in diets fed to lactating dairy cows was reviewed. Potential modifying effects of corn silage, starch...

N UMEROUS communications from this laboratory, Burroughs et al. (I949a, I949b, I949c, I95oa, I9~ob, and I9~oc) have called attention to the influence of nutrients needed by rumen microorganisms in the digestion of roughages, particularly the cellulose fraction. Hungate (I9~o), after extensively reviewing the literature pertaining to rumen cellulose digesting bacteria, concluded that: "Further i...

Several feed ingredients have been investigated in an attempt to substitute fishmeal in the diets of fish and livestock. These include both animal protein and plant protein sources. Unfortunately attempts to use these ingredients for complete replacement of the fishmeal component in tilapia diets have not entirely been successful. A major reason is the suboptimal content of essential amino acid...

Three experiments of 28 days duration were conducted in three size groups (<1g, 1-5g and 5-10g) of Indian white shrimp, Fenneropenaeus indicus, to evaluate the appropriate protein: energy (GE) ratios in their diets. A common ingredient mixture consisting of fish meal, shrimp meal, ground nut oil cake, cholesterol, lecithin, vitamins and minerals blended with chicken egg albumin, tapioca flour a...

this study was conducted to determine in vitro crude protein degradation (ivdp) parameters and effective crude protein degradability (epd) of various feeds using the modified in vitro gas production (gp) technique. feed samples were alfalfa hay, soybean meal, soybean, rapeseed meal, sunflower meal and fish meal. rumen fluid was collected before the morning feeding from four rumen fistulated lam...

Background: Several health problems may be occurred due to consumption of mycotoxin-contaminated foods and feeds. The maize and oilseeds, as the main components of poultry feeds are susceptible to mould contamination and mycotoxin production. The aim of this study was to determine the presence of toxigenic Aspergillus spp. in poultry feeds from Ilaro, Nigeria. Methods: A total of 60 poultry fe...
